Impact Target Sensor Nesting for Sensitivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports simulator impact targets often have vibration sensors positioned on the rear surface, which reduces sensitivity and effectiveness in detecting impacts from sports projectiles.
Innovation Solution
The impact target features a vibration sensor positioned within an opening that extends through the thickness of the plate from the rear surface to the front surface, enhancing sensitivity by locating the sensor closer to the impact surface and improving vibration detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the vibration sensor is positioned on the rear surface of the plate, then the sensor is easier to mount and protect, but the sensitivity and effectiveness in detecting impacts is reduced
Solution Approach 1:
The patent transitions the sensor positioning from a two-dimensional rear surface mounting to a three-dimensional opening-based positioning that extends through the plate thickness. This allows the sensor to be located closer to the impact surface (front surface) while still being protected within the plate structure, thereby improving sensitivity without excessive complexity
Solution Approach 2:
The vibration sensor is nested within an opening that extends through the plate thickness, with the sensor positioned inside this recessed space. This nesting approach allows the sensor to be closer to the impact surface while remaining protected within the plate structure, resolving the contradiction between sensitivity and mounting complexity
2Measurement precision
If the vibration sensor is positioned closer to the impact surface, then the sensitivity improves, but the sensor becomes more vulnerable to damage from high-impact forces
Solution Approach 1:
The sensor is nested within an opening that extends through the plate thickness, positioning it closer to the impact surface while providing protective enclosure within the plate structure. This nested configuration allows the sensor to benefit from closer proximity to impacts while being shielded from direct damage
Solution Approach 2:
The opening structure serves as a pre-configured protective element that cushions and distributes impact forces before they reach the sensor. By having this protective structure in place beforehand, the sensor is protected from direct high-impact forces while still being able to detect vibrations from legitimate sports projectile impacts
